The heat battery is not yet commercially available. We are working hard to have a user-ready-prototype available soon. This will take at least another 2 years. The user-ready prototype will need to be tested by end-users and depending on the results, the product will be available for the consumer. In terms of translating the technology into a product and bringing it to the market, we expect to see the first real market applications from 2025 onwards.
The boundary conditions of the HEAT-INSYDE project, within the framework of Horizon 2020, include delivering a heat battery for residential applications. However, we are seeing that there are several other application opportunities, such as in utility buildings, greenhouses and off-grid locations. To bring the technology to the market we introduced a new business vehicle, Cellcius B.V., as a new partner in the consortium. Cellcius is in place to bring this technology to the market but will also explore a variety of applications in different market segments from the one defined for HEAT-INSYDE.
